At State and Water streets, you’ll find a perpetual “Animal House” party scene.

But no worries: the shindig never gets off-the-wall. That’s because it’s on the wall.

A mural — 50 feet long by 17 feet high — graces a corner of the five-building complex that goes by the name Le Vieux Carre (French for “The Old Square”). The 2000 work, by artists Lonnie Stewart and Mariam Graff, sports a Mardi Gras theme as a nod to the French history of the riverfront. The work traces traditions of Mardi Gras, with stops in Greece, France, Italy and New Orleans. Leopards, pigs and peacocks mingle with raucous, dancing revelers.

The mural also includes several local personalities. The most obvious is late councilman Gary Sandberg — a stand-in for Bacchus, the Roman god of wine — astride a mule. He wears a crown of grapes and carries a goblet in one hand and a daisy in the other. One eyebrow cocked slyly, he seems to know that this party will never end.
